	/*return _CF_checkprogform(document.progform); is a hack, but it passes control back to the form.  It's what coldfusion puts in the form tag, except i substituted "document.progform" for "this".  If i put in:
	
				document.progform.submit();
				
	up above, it will not pass control back properly.  It will let the form submit without the coldfusion checks.  Coldfusion has Progform say 'this' on the page (Verbatim:****   onSubmit="return _CF_checkprogform(this)  *****[although i'm not sure this line is even used, as my line below may be the one of the two that does the submit]), so in the <cfform> tag (preprocess), i put:
	
				 onsubmit="document.progform.submit();"
	
	This is inserted by coldfusion right before its last "return true;"  Putting "this" in there would kill it, even though it resides in the proper element, as it does get passed up to the top of the page.
	
	Called from form's submit button:   <input type="button" value="submit" class="steelsubmitbutton" onClick="functioncontrol();">
